USB to RS-485 Interface Converter with RJ-45 port

The AN-USB-RS485-RJ45 module is a cost-effective way to convert RS485 industrial buses to a USB interface.


The AN-USB-RS485-RJ45 module is a cost-effective way to convert RS485 industrial buses to a USB interface. When connected to a PC USB port the AN-USB-RS485-RJ45 module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application. Multiple modules can be installed when using USB hubs thus allowing a hassle free configuration of a multi serial system without any IRQ or DMA configuration.


   The AN-USB-RS485-RJ45 converter can be configured for RS485  two-wire (Half Duplex) networks. When operating in two-wire RS485 the data transfer control is automatically done by the converter. Two independent and RS485 networks can be supported by one AN-USB-RS485-RJ45 module thus duplicating possible number of remote devices.
